Special Issue Information
Dear Colleagues,
Many high-order nonlinear phenomena, including high harmonic generation, tunneling ionization, double ionization, laser-induced electron diffraction, and laser-induced ultrafast current, among others, can occur when a powerful femtosecond laser interacts with gaseous, aqueous, or solid objects. Novel experimental approaches have been developed to inspect the signals of ions, electrons, or photons within ultrashort timescales. The most reliable methodology for modeling the experimental observables is to solve a time-dependent Schrodinger equation (TDSE) or another enlarged dynamic equation. To make the physical process easier to grasp, several semi-analytic models have also been proposed.
The output signal is primarily influenced by the symmetry property of the target, making it natural to analyze experimental or numerical data from a symmetry perspective. As our understanding of the connection between the target's symmetry property and the characteristics of an ultrafast signal deepens, predicting the features of the output signal becomes more feasible. Furthermore, the ultrafast output signal can serve as an effective tool for detecting the symmetry property of an unknown target. In particular, achieving ultrafast time-resolution in monitoring phase transitions, while considering changes in the symmetry property, necessitates the study of the causal relationship between the sample's symmetry and the features observed in the output signal.
In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following: space-time symmetry, nonlinear interaction, strong-field ionization, high harmonic generation, time-resolved spectroscopy, and electron dynamics.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Symmetry is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
